BFI Optilas is offering a range of broadband low-dispersion polarisers and super-broadband polarising beamsplitter cubes.
New capabilities include batch size polishing of fused silica, Terbium Gallium Garnet (TGG), single crystal sapphire (Al2O3) and Ti Sapphire glass.
Plano substrates of up to 3in diameter can be polished to better than 10 surface flatness with 10-5 surface quality and surface roughness of less than 1 angstrom RMS.
Super-polished or laser-quality polished substrates and assemblies are ideal for use as low-loss laser mirrors, high-energy waveguides and in cavity ring-down spectroscopy (CRDS) where thermal stability, surface scatter and high laser damage thresholds are key requirements.
BFI can also provide ion-beam-sputtered (IBS) anti-reflection, beam splitter and high-reflection coatings on these and other materials at wavelengths from 266nm to more than 3um.
